随着越来越多的深度学习对在设备上的Tinyml应用程序的采用,人们对对边缘进行优化的更有效的神经网络骨架的需求不断增加。最近,注意力冷凝器网络的引入导致低英寸,高效,自我发挥的神经网络,在准确性和速度之间取得了强大的平衡。在这项研究中,我们介绍了一种新的更快的注意力冷凝器设计,称为双感应注意力冷凝器,以实现更多的冷凝特征嵌入。我们进一步采用了机器驱动的设计探索策略,该策略施加了最佳实践设计限制,以提高效率和稳健性,以产生骨干的宏观构造结构。与其他几个其他最先进的有效骨架相比,所得的主链(我们命名为“参加”)在嵌入式ARM处理器上的推理吞吐量明显更高(以较高的精度和速度比FB-NET C快> 10倍)小型型号尺寸(以较高的速度和类似的精度小于OFA-62小1.47倍),并且准确性(以更高速度的ImageNet上的MobileVit Xs高1.1%)。这些有希望的结果表明,探索不同的有效体系结构设计和自我注意力的机制可以为Tinyml应用带来有趣的新构建块。

现代深度神经网络必须展示最先进的准确性,同时表现出低延迟和能耗。因此,在生成新架构时,神经结构搜索(NAS)算法将这两个约束考虑在内。但是,诸如延迟的效率度量通常是依赖于需要NAS算法来测量或预测架构延迟的硬件。测量每个评估架构的延迟增加了NAS过程的大量时间。在这里,我们将微处理器提出了一个先验的延迟估计枫木,其不依赖于传输学习或域适应,而是通过在训练期间结合先前的硬件特征来推广到新硬件。枫木利用新的定量策略来通过测量相关的硬件性能度量来表征底层微处理器,产生细粒度和富有效应硬件描述符。此外,所提出的枫木从CPU和GPU之间的紧密耦合I / O以及它们在从CPU中测量GPU硬件的微处理器性能硬件计数器时预测GPU上的DNN延迟的依赖性。通过这种定量策略作为硬件描述符,Maple可以通过一些镜头适应策略概括到新硬件,其中少于3个样本,它具有超过最先进的方法的3%改进,需要多达10个样品。实验结果表明,随着最先进的方法,增加了几次喷射适应样品到10提高了精度12%。此外,据证明,与任何数量适应样品的相关基线相比,枫木呈现出8-10%的精度,平均相比。

The recent increase in public and academic interest in preserving biodiversity has led to the growth of the field of conservation technology. This field involves designing and constructing tools that utilize technology to aid in the conservation of wildlife. In this article, we will use case studies to demonstrate the importance of designing conservation tools with human-wildlife interaction in mind and provide a framework for creating successful tools. These case studies include a range of complexities, from simple cat collars to machine learning and game theory methodologies. Our goal is to introduce and inform current and future researchers in the field of conservation technology and provide references for educating the next generation of conservation technologists. Conservation technology not only has the potential to benefit biodiversity but also has broader impacts on fields such as sustainability and environmental protection. By using innovative technologies to address conservation challenges, we can find more effective and efficient solutions to protect and preserve our planet's resources.

We outline our work on evaluating robots that assist older adults by engaging with them through multiple modalities that include physical interaction. Our thesis is that to increase the effectiveness of assistive robots: 1) robots need to understand and effect multimodal actions, 2) robots should not only react to the human, they need to take the initiative and lead the task when it is necessary. We start by briefly introducing our proposed framework for multimodal interaction and then describe two different experiments with the actual robots. In the first experiment, a Baxter robot helps a human find and locate an object using the Multimodal Interaction Manager (MIM) framework. In the second experiment, a NAO robot is used in the same task, however, the roles of the robot and the human are reversed. We discuss the evaluation methods that were used in these experiments, including different metrics employed to characterize the performance of the robot in each case. We conclude by providing our perspective on the challenges and opportunities for the evaluation of assistive robots for older adults in realistic settings.

The acquisition of high-quality human annotations through crowdsourcing platforms like Amazon Mechanical Turk (MTurk) is more challenging than expected. The annotation quality might be affected by various aspects like annotation instructions, Human Intelligence Task (HIT) design, and wages paid to annotators, etc. To avoid potentially low-quality annotations which could mislead the evaluation of automatic summarization system outputs, we investigate the recruitment of high-quality MTurk workers via a three-step qualification pipeline. We show that we can successfully filter out bad workers before they carry out the evaluations and obtain high-quality annotations while optimizing the use of resources. This paper can serve as basis for the recruitment of qualified annotators in other challenging annotation tasks.

Achieving artificially intelligent-native wireless networks is necessary for the operation of future 6G applications such as the metaverse. Nonetheless, current communication schemes are, at heart, a mere reconstruction process that lacks reasoning. One key solution that enables evolving wireless communication to a human-like conversation is semantic communications. In this paper, a novel machine reasoning framework is proposed to pre-process and disentangle source data so as to make it semantic-ready. In particular, a novel contrastive learning framework is proposed, whereby instance and cluster discrimination are performed on the data. These two tasks enable increasing the cohesiveness between data points mapping to semantically similar content elements and disentangling data points of semantically different content elements. Subsequently, the semantic deep clusters formed are ranked according to their level of confidence. Deep semantic clusters of highest confidence are considered learnable, semantic-rich data, i.e., data that can be used to build a language in a semantic communications system. The least confident ones are considered, random, semantic-poor, and memorizable data that must be transmitted classically. Our simulation results showcase the superiority of our contrastive learning approach in terms of semantic impact and minimalism. In fact, the length of the semantic representation achieved is minimized by 57.22% compared to vanilla semantic communication systems, thus achieving minimalist semantic representations.

With the evolution of power systems as it is becoming more intelligent and interactive system while increasing in flexibility with a larger penetration of renewable energy sources, demand prediction on a short-term resolution will inevitably become more and more crucial in designing and managing the future grid, especially when it comes to an individual household level. Projecting the demand for electricity for a single energy user, as opposed to the aggregated power consumption of residential load on a wide scale, is difficult because of a considerable number of volatile and uncertain factors. This paper proposes a customized GRU (Gated Recurrent Unit) and Long Short-Term Memory (LSTM) architecture to address this challenging problem. LSTM and GRU are comparatively newer and among the most well-adopted deep learning approaches. The electricity consumption datasets were obtained from individual household smart meters. The comparison shows that the LSTM model performs better for home-level forecasting than alternative prediction techniques-GRU in this case. To compare the NN-based models with contrast to the conventional statistical technique-based model, ARIMA based model was also developed and benchmarked with LSTM and GRU model outcomes in this study to show the performance of the proposed model on the collected time series data.

Boundary conditions (BCs) are important groups of physics-enforced constraints that are necessary for solutions of Partial Differential Equations (PDEs) to satisfy at specific spatial locations. These constraints carry important physical meaning, and guarantee the existence and the uniqueness of the PDE solution. Current neural-network based approaches that aim to solve PDEs rely only on training data to help the model learn BCs implicitly. There is no guarantee of BC satisfaction by these models during evaluation. In this work, we propose Boundary enforcing Operator Network (BOON) that enables the BC satisfaction of neural operators by making structural changes to the operator kernel. We provide our refinement procedure, and demonstrate the satisfaction of physics-based BCs, e.g. Dirichlet, Neumann, and periodic by the solutions obtained by BOON. Numerical experiments based on multiple PDEs with a wide variety of applications indicate that the proposed approach ensures satisfaction of BCs, and leads to more accurate solutions over the entire domain. The proposed correction method exhibits a (2X-20X) improvement over a given operator model in relative $L^2$ error (0.000084 relative $L^2$ error for Burgers' equation).

In post-covid19 world, radio frequency (RF)-based non-contact methods, e.g., software-defined radios (SDR)-based methods have emerged as promising candidates for intelligent remote sensing of human vitals, and could help in containment of contagious viruses like covid19. To this end, this work utilizes the universal software radio peripherals (USRP)-based SDRs along with classical machine learning (ML) methods to design a non-contact method to monitor different breathing abnormalities. Under our proposed method, a subject rests his/her hand on a table in between the transmit and receive antennas, while an orthogonal frequency division multiplexing (OFDM) signal passes through the hand. Subsequently, the receiver extracts the channel frequency response (basically, fine-grained wireless channel state information), and feeds it to various ML algorithms which eventually classify between different breathing abnormalities. Among all classifiers, linear SVM classifier resulted in a maximum accuracy of 88.1\%. To train the ML classifiers in a supervised manner, data was collected by doing real-time experiments on 4 subjects in a lab environment. For label generation purpose, the breathing of the subjects was classified into three classes: normal, fast, and slow breathing. Furthermore, in addition to our proposed method (where only a hand is exposed to RF signals), we also implemented and tested the state-of-the-art method (where full chest is exposed to RF radiation). The performance comparison of the two methods reveals a trade-off, i.e., the accuracy of our proposed method is slightly inferior but our method results in minimal body exposure to RF radiation, compared to the benchmark method.

本文考虑通过模型量化提高联邦学习(FL)的无线通信和计算效率。在提出的Bitwidth FL方案中,Edge设备将其本地FL模型参数的量化版本训练并传输到协调服务器,从而将它们汇总为量化的全局模型并同步设备。目的是共同确定用于本地FL模型量化的位宽度以及每次迭代中参与FL训练的设备集。该问题被视为一个优化问题,其目标是在每卷工具采样预算和延迟要求下最大程度地减少量化FL的训练损失。为了得出解决方案,进行分析表征,以显示有限的无线资源和诱导的量化误差如何影响所提出的FL方法的性能。分析结果表明,两个连续迭代之间的FL训练损失的改善取决于设备的选择和量化方案以及所学模型固有的几个参数。给定基于线性回归的这些模型属性的估计值,可以证明FL训练过程可以描述为马尔可夫决策过程(MDP),然后提出了基于模型的增强学习(RL)方法来优化动作的方法选择迭代。与无模型RL相比,这种基于模型的RL方法利用FL训练过程的派生数学表征来发现有效的设备选择和量化方案,而无需强加其他设备通信开销。仿真结果表明,与模型无RL方法和标准FL方法相比,提出的FL算法可以减少29%和63%的收敛时间。
